L l O I 1 I6 26 26 I6 1 NEEDLE-BEDS FOR DOMESTIC KNITTING MACHINES Thisinvention relates to domestic knitting machines having needle beds ofbox form for a series of needles or sinkers.

The beds of these machines are usually made of sheet metal with guidingmeans for needles or sinkers, consisting of a series of slots formed inthe upper plate of the bed, which slidably receives the butts of theneedles or sinkers.

The camslide which, as it is oscillated along the bed, projects andretracts the needles or sinkers, is usually engaged in guides on theupper plate, which are added to the plate and secured in position.

The object of the present invention is to provide a needle bed withwhich the camslide may be directly engaged and which is, therefore,simpler in construction than the usual arrangement.

According to the invention, the upper plate of the bed overhangs the bedat both back and front of the bed, and each overhang constitutes a guidefor the camslide.

FIGS. l-5 show various cross-sectional views of the embodimens of theinvention.

Various fonns of the invention are illustrated in the accompanyingdrawings. In FIG. I, the bed is a box composed of a trough-shaped base10, which may be unitary or made up of different parts connectedtogether, and an upper plate 12 secured inwardly turned flanges 14 onthe sides 16 of the trough. The plate 12 projects beyond the trough toprovide flanges 18 which are engaged by the camslide 20 which is formedwith recesses 21 engaged over the flanges 18, to permit the camslide tobe oscillated freely but without significant play.

ln FIG. 2, both flanges 14 are directly forwardly. ln FIG. 3, bothflanges l4 are directed rearwardly. In FIG. 4, the flanges I4 are bothturned outwardly. In FIG. 5, there is a double flange 22 at the top ofeach side, each secured to the plate 12.

All the constructions serve the same purpose, namely, to provide guidesfor the camslide without structure additional to the upper plate.

Needles 24 are slidably mounted in slots 26.

I claim:

I. A needle bed for a domestic knitting machine comprising a box sectionlower portion having upstanding parallel sidewalls, a slotted upperplate which is wider than and formed separately from the lower portion,resting on the sidewalls with the latter spaced from the edges of theupper plate so that laterally projecting flanges are formed at each sideof the upper plate, and securing means securing the upper plate to thesidewalls.

2. A needle bed as claimed in claim 1 in which the lower portion wallshave laterally projecting flanges and the securing means connects theupper plate to the flanges.

3. A needle bed as claimed in claim 2 in which the securing means arescrews.

4. A domestic knitting machine comprising a needle bed as claimed inclaim 1 and a camslide with parallel longitudinal recesses whichslidable receive the flanges.

1. A needle bed for a domestic knitting machine comprising a box sectionlower portion having upstanding parallel sidewalls, a slotted upperplate which is wider than and formed separately from the lower portion,resting on the sidewalls with the latter spaced from the edges of theupper plate so that laterally projecting flanges are formed at each sideof the upper plate, and securing means securing the upper plate to thesidewalls.
 2. A needle bed as claimed in claim 1 in which the lowerportion walls have laterally projecting flanges and the securing meansconnects the upper plate to the flanges.
 3. A needle bed as claimed inclaim 2 in which the securing means are screws.
 4. A domestic knittingmachine comprising a needle bed as claimed in claim 1 and a camslidewith parallel longitudinal recesses which slidable receive the flanges.
